Chemically, black carbon (BC) is a component of fine particulate matter (PM ≤ 2.5 µm in aerodynamic diameter). Black carbon consists of pure carbon in several linked forms. It is formed through the incomplete combustion of fossil fuels, biofuel, and biomass, and is one of the main types of particle in both anthropogenic and naturally occurring soot. Black carbon causes human morbidity and premature mortality.
The researchers developed a special substance that could be applied to roads to help cut high concentrations of polluting gases released into the atmosphere. Called a photocatalytic pavement, the technology was tested in the urban area of the city of Hengelo, in the east of the Netherlands. According to the
